New EPA chief has also enjoyed “very cozy” relationship with billionaire Koch Bros.

According to thousands of emails made public on Wednesday, former Oklahoma attorney genera Scott Pruitt, —now the head of the Environmental Protection Agency—closely “coordinated with major oil and gas producers, electric utilities and political groups with ties to the libertarian billionaire brothers Charles G. and David H. Koch to roll back environmental regulations,” reports the New York Times.

The EPA, of course, is charged with reining in pollution and regulating public health.

Over 6,000 email correspondences capture just how opposed Pruitt was to most the agency’s efforts to regulate energy producers in America and just how cozy he still is with the very industries he is now responsible for policing.
